Four things to keep in mind:

1. HMs and the like: They usually aren't very helpful for competitive use. Get rid of Garchomp's False Swipe and Rock Smash, and Zoroark's Rock Climb.

2. Unevolved Pokemon: Evolve your Riolu immediately!! If you don't want to evolve Riolu because you prefer Riolu over Lucario, then do not use that Riolu competitively.

3. Megas: You should only have one Mega, since more means wasted item slots. Pick either Mega Charizard X or Mega Gardevoir.

4. Items: Items are extremely useful in battles. Your Zoroark needs an item, and your Riolu and Garchomp also need better items.

Overall, I feel that you and your team have great potential. Below this comment, there is plenty of advice from your fellow wiki members that you can sift through. Just remember not to get too defensive.
